[0035] In this embodiment, the connecting mechanism 3 is convenient to connect with the expansion mechanism 4, and the detachable structure between the connecting mechanism 3 and the expansion mechanism 4 makes the expansion mechanism 4 can be disassembled from the connecting mechanism 3 for disinfection and sterilization treatment after use, so that the expansion mechanism 4 can be repeatedly used, and in the whole device, only the expansion mechanism 4 needs to be disinfected and cleaned, which can reduce the difficulty of disinfection;

[0036] Specifically, when installing the expansion mechanism 4, first, the butt piece 41 of the expansion mechanism 4 is aligned with the connecting seat 31 of the connecting mechanism 3 and inserted, the depth of the butt piece 41 inserted into the connecting seat 31 is determined according to the specific use, then the position between the expansion mechanism 4 and the connecting mechanism 3 is locked by tightening the locking rod three 35, and the connecting rod 32 is rotatably connected to the connecting seat 31, so that the connecting rod 32 can be rotated by the connecting seat 31 to change the pitch angle, thereby driving the expansion mechanism 4 to pitch, after the adjustment is completed, the connecting seat 31 is locked by tightening the locking rod two 33, so as to ensure that the pitch angle of the expansion mechanism 4 does not change, and the rotation of the connecting rod 32 can be controlled by holding the handrail two 34.

[0037] Please refer to Figure 5 As shown, the expansion mechanism 4 includes a butt piece 41 inserted in the connecting rod 32, the butt piece 41 and the connecting rod 32 are detachable structure, the distal end of the butt piece 41 is fixedly installed with the expansion claw one 42, the butt piece 41 is movably connected with the expansion claw two 43, the inner side of the butt piece 41 is rotatably connected with the lead screw 44, and the lead screw 44 and the expansion claw two 43 are threadedly engaged;

[0038] In this embodiment, the expansion mechanism 4 is an important component for expanding the patient's ribs. When the patient's ribs are expanded, the expansion claw 42 and the expansion claw 43 are placed between the ribs, and then the force lever 45 is pulled to drive the screw rod 44 to rotate. Since the screw rod 44 is in threaded engagement with the expansion claw 43, the expansion claw 43 can be driven to move away from the expansion claw 42 along the abutting piece 41, thereby expanding the patient's ribs.

[0039] The working principle of the utility model is as follows: during the operation of a patient, in order to expand the patient's ribs to facilitate the operation, the rib expander is used to expand the patient's ribs to provide a space for the doctor to operate.
